A method for the production of micro capsules by atomizing an aqueous soluti on (1) containing 0.1-5 wt. % of at least one water-soluble polyanion to form liquid droplets. The liquid droplets thus obtained impinge upon a liquid fil m of an aqueous solution (2), containing: 0.1-5 wt. % calcium cations, 0.001-0 .4 wt. % chitosane with a molecular weight of more than 40,000 g/mol, and/or 0. 1- 5 wt. % chitosane with a average molecular weight of 500-40,000 g/mol.</SDOA B>
